Abstract: Because of its high gas outlet temperature, the HTR reaches beyond sheer power production and opens up long-range prospects in the field of new coal refining techniques. The AVR-reactor is remarkably suited to be used for nuclear process heat due to its infrastructural and scientific insertion into the Kernforschungsanlage Jülich. To decide whether or not the AVR-reactor should continue operation or be remodelled into a process heat plant, the present state and the expectation of life for the whole facility has beenanalysed by many detailed investigations. This study deals with the increase of stress in the AVR topreflector with respect to the past service life history, and provides results on stresses which cover a convenient spectrum of reactor operations in the future. The calculations have been done with a three-dimensional geometry in considération of the anisotropic material behavior and the influence of creep by radiation. Using adequate stress criteria it can be stated, even though conservative assumptions where taken into account, that a sufficient expectation of life for the topreflector can be warranted.
